AN EXPEDITION TO MOUNT BATU. LAWI. 35 
measures 150 mm., while vertex of head to end of abdomen measures 
48 mm.), it was rather surprising that the web should hold it so 
effectually . Belulok caught a large Sphingid (Hawk-moth, Oxy- 
ambulyx substrigilis, Westw.) by the side of the path. Rain again 
in the afternoon which developed into a heavy thunderstorm as we 
stopped to make a lancho for the night (alt. 3,100 ft.), and now as 
I write (8 p.m.) it has started again with renewed vigour. We 
passed little streams or pools of water in two or three places on the 
way and I pointed out that the first or second would have done well 
for last night’s lancho. At 2 o’clock this afternoon we came to one 
and the Kalabits wanted to stop with the same excuse as yesterday, 
but this time I said he would push on till we did find some more 
water. With our short supply of food, the long distance to be 
covered and the uncertainty of the path, it is necessary to push on 
at every opportunity. 
May 24th: (Temp. 6 a.m. 67°). Several of the party with 
bad colds, and cuts and sores on their feet, but generally cheerful. 
Our path to-day leads along the top of a ridge at a fairly even 
altitude of 3,100 ft. for two hours; then up to 3,700 ft. and after 
a short descent we have another long climb up to the summit of 
this part, 4,000 ft., which according to Penribut is called Mt. 
Turan. 
Although the natives with me have not been able to recognize 
any of St. John’s names for the mountains of this part, I think St. 
John must have reached this range and then turned north towards 
the Adang villages. His route appears to have run parallel to 
mine from the Madihit to the Limbang, only further to the north 
and over a lower country as he records 2,500 ft. as the highest 
altitude crossed between the two rivers, while we have already 
touched 4,000 ft. (and later 5,000 ft.) without coming to the 
Iimbang yet. Our general direction is stil] East. and the 
path shut in on all sides by old jungle prevents our obtain- 
ing any veiw except for an oceasional glimpse though the 
trees on some of the higher elevations. We camp late in 
the afternoon to the usual accompaniment of pouring rain 
(alt. 3,900 ft.). Thermometer down to 67° at sunset. One of 
the collectors shot a rare Oriole (Oriolus hosei, Sharpe). Rarely 
seen or hear any signs of animal life, except for the occasional cry 
of a Wa-Wa (LHylobates miilleri, the Gibbon). Water has not been 
found all day, except just now at a little pool some way below our 
present camp, and we have had to satisfy ourselves with some 
from the roots of trees, which hold quite a lot when one cuts off 
lengths of the right kind. Penribut says we shall reach the river 
Kri to-morrow where we shall see the whole of Batu Lawi quite 
close; he does not know the path any further than that. ‘T’emper- 
ature 67° at sundown. 
May 25th: (6 a.m. temp. 65.5°). Left camp early and at once 
continue the ascent reaching 4,460 ft., the head-waters of the 
Madihit are pointed out running parallel to us in the valley below
